c# - 从远程机器检索进程信息和文件

Question

我正在尝试使用以下代码检索特定进程:

Process[] Process = Process.GetProcessesByName(_ProcessName, _Ip);

当_Ip为“127.0.0.1”时，进程获取成功。当_Ip表示远程机器时，出现如下异常:

System.InvalidOperationException occurred
  HResult=-2146233079
  Message=Couldn't connect to remote machine.

我尝试执行以下操作:

1. 两台机器之间Ping – 成功

2. 在远程机器上取消防火墙

3. 在两台机器上启用并启动“Remote Registry”服务

检索进程的目的是找到它的目录路径并使用以下代码行读取位于该目录中的日志文件:

FileStream fStream = new FileStream(fileInfo.FullName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);

希望你已经尝试过Process Information on Remote Computer.它说正确的方法是使用 WMI。

此链接有很好的示例，它使用 System.Management 连接到远程系统并获取进程详细信息。
